cycloplegic refraction

This is the method for checking glasses prescription in children.  Children have strong muscles inside their eye that make it hard to measure their vision during a refraction. They can “strain” while reading the eye chart, throwing off our measurements. By using cycloplegia dilation drops, we temporarily paralyze these eye muscles and can capture a more accurate glasses check.  Many children require their eyes to be dilated this way and this can really extend your office visit time tremendously.
